FRAME AND CORNER-IRONS THEREFOR.

To all whom it may concern Be it known that I, Fran; P. DARGY, a citizen of the United States, residing in the city and county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Frames and Cornerlrons Therefor, of which the following is a specification.

This invention relates to improvements in frames and corner irons therefor.

My improved frame is especially designed by me for use in cushion seats for automobiles, carriages and'the like, where it is desirable to have a light rigid frame. In cushions of this character, using helically coiled springs, the springs are frequently mounted on supports, such as are shown in my Patent No. 726,817, issued on the 728th day of April, 1903, adapted to be nailed to the frame.

It is the main object of this invention to provide an improved frame which is sim ple and economical in structure and at the same time, strong and rigid, and one which,

. while having these advantages, may be constructed of comparatively light material.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

Lin

I accomplish the objects of my invention by the means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodi- 1' ment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is a perspective view of a frame embodying the features of my invention. Fig. 11 is a detail perspective view of a pair of meeting frame pieces showing the manner of forming the joints with the corner irons in position. Fig. 111 is a perspective view of one of'the corner irons. Fig. IV is a perspective view of a coacting corner iron. Fig. V is a detail section on a line corresponding to line -5 of Fig. H, showing structural details. Fig. V1 is a detail horizontal section on a line corresponding to line 66 of Fig. 11, showing further details. Fig. VII is a perspective view of a slightly modified structure. Fig. VIII is a detail section corresponding to that of Fig. V, of another modified form of my invention.

Serial No. 67,404.

In the drawing similar reference characters refer to similar parts throughoutthe several views, and the sectional views are :taken looking in the direction of the little arrows at the ends of the section llnes.

Referring to the drawing, the frame shown is rectangular, being formed of four frame pieces 1. These frame pieces are joined by rabbeted lap j oints, the pieces having rabbets 2 at each end forming tongues 3, which are lapped, as shown in Fig. I. The corner irons & and 5 are plate-like in form, being preferably circular so as to 0bviate corners, and are provided with angularly disposed flanges 6 and 7, respectively. These flanges are adapted to engage the inner edges of meeting frame pieces when the plates are arranged on the sides thereof. In other words, the flanges are disposed at angles to each other corresponding to the angles of the frame pieces, the angles in the structure illustrated being right angles.

The corner irons are arranged in opposed pairs on the sides of meeting frame pieces with their flanges in overlapping telescoping relation on the inner edges of the frame pieces. frame pieces by the nails 8. The flanges 6 are provided with a series of teeth or brads 9 which are driven into the frame pieces. The flanges 6 are also preferably provided with vertical slots 10, while the flanges 7 of the coacting plate 5 have nail holes 11, which register with the slots 10, so that nails 12 may be driven through the nail holes and slots into the frame pieces as clearly shown in Fig. V.

By making the nail holes slot-like in form the. corner irons can be adjusted to frame pieces of different thickness and in rough lumber such as is commonly used in the manufacture of these frames there is considerable variation in stock. However, as the corner iron flanges are arranged in over lapping telescoping relation to each other the corner irons readily accommodate themselves to these variations. The frame pieces are thus secured and rigidly connected and braced and connected at the joints and are well adapted to withstand the racking strains to which they are subject in use.

In practice the corner irons are formed of sheet metal stampings and I have found that scrap metal, ordinarily considered as The corner irons are secured to the quite useless can be satisfactorilyiused for,

the purpose,thus further reducing the cost of material. r

The dies for forming the corner irons can frames may be quickly assembled, and the corner irons applied. a 1 t' l In the modification shown in Fig. VIII the corner iron flanges are arranged in the same telescoping overlapping relation, but the feature of the brads and the long nail.

I have not attempted to illustrate or describe various applications of my improvements which I contemplate as advantageous or desirable, as I believe the disclosuremade Willenahle those skilled in the artlto embody my invention as circumstances may requlre. Having thus descrlbed my invent on, What 7 I'claim'as new and desire to secure by Letters Patent, is:
